Why do so many of the world's religions ban eating pork?
What is it about pork that it would feature so highly on a meta list of religiously banned foodstuffs? Are there other foods that are also commonly banned? I’m not really wondering about the reasons that religions give for not eating pork (though these might give clues) but why it would feature in so many.
